MicroSurvey can save and work directly in DWG format. We can also create the standard Point Block that LDD (softdesk/DCA) has used for many years. The QSB file is not something that can be used by LDD but if you simply draw the TIN into the DWG, Softdesk can extract it to create the same TIN, very easily.

The reverse is also true - we can read the DWG files created in LDD, read the standard point blocks to create our point database, and we can extract pretty much any items in the drawing to form a TIN.

We have many customers that do work in both programs or exchange data with companies using LDD.
